VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 633,617, datedSeptember 26, 1899.

Application filed May 21, 1898. Serial No. 681,321. (No model.) I

To whom it may concern:

Be it known that I, WILLIAM SCOTT, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented a new and useful Vapor-Burner, of which the following is aspecification.

This invention relates to that class of illuminatin g apparatus ordevices which convert a hydrocarbon into vapor prior to consuming thesame at the escaping-orifice.

The purpose of the invention is to secure a soft light of good qualityand to economize in the consumption of the oil proportionate to theeffective light obtained.

The invention also has for its object to provide for a nicety ofadjustment of the parts, so that no waste of vapor is possible and theproper amount of air at a suitable temperature may be intermixedtherewith, so as to secure the required combustion essential to theproduction of a flame of great illuminating power.

For a full understanding of the merits and advantages of the inventionreference is to be had to the accompanying drawings and the followingdescription.

The improvement is susceptible of various changes in the form,proportiomand the minor details of construction without departing fromthe principle or sacrificing any of the advantages thereof, and a fulldisclosure of the invention and adaptation thereof is shown in theaccompanying drawings, in which- Figure 1 is a sectional detail of alamp or illuminating device constructed in accordance with thisinvention. Fig. 2 is a detail view of the generator. Fig. 3 is a detailview in perspective of the body portion of the burner, parts beingbroken away. Fig. 4c is a; detail view of the gallery, the sleeveconnected therewith and rotatably mounted upon the body portion of theburner, and the lower portion of the shade-holder. Fig. 5 is a sectionaldetail of the burner, the upper portion of the chimney-holder beingbroken away. Fig. 6 is a detail view, partly in section, of the adjustable vapor-burning pipe.

Corresponding and like parts are referred to in the followingdescription and indicated in the several views of the accompanyingdrawings by the same reference characters.

The reservoir or fount for containing the oil is represented by thenumeral 1 and is shown provided with a stem 2, having an eye at itsupper end to receive a hook, pin, or like device from which the lamp issuspended. The fount is provided with an opening in its upper portionwhich is closed by means of a screw cap or plug 3. A pipe 11 connectswith the lower portion of the fount and is provided at its lower endwith a T-coupling 5, to which pipes 6 and 7 connect. T-couplings S and 9are fitted to the lower ends of the pipes 6 and 7 and have other pipes10 and 11 connected therewith. A T-coupling 12 joins the lower ends ofthe pipes 10 and 11 and has a burner of any desired pattern, make, orstyle applied thereto.

A generator is located above the burner and consists of ahorizontally-disposed pipe 13, secured at its outer end to theT-coupling 8 and having its inner end made tapering,

as shown at 14, and terminating a little to one side of a line passingvertically through the burner, but in the path of heated air. risingtherefrom. A needle-valve 15 is located within the pipe 13, and itsinner end is made tapering to close the orifice formed at the extremityof the tapering end 14 of the generator. This valve is slidingly mountedin the pipe 13 and in a stuffing-box l6, fitted to the T-coupling 8, andconnects at its outer end with a bow-spring 17, which is made fast atone end of the T-coupling 8 and is movable at its opposite end by meansof a setscrew 18. The spring 17 normally exerts an inward pressureagainst the valve 15, so as to hold its tapering end seated against theinner portion of the tapering end 14 of the generator, thereby cuttingoff all escape of the oil or vapor. It is obvious that the needlevalvemay be operated by any of the means commonly employed in apparatus forburning hydrocarbon after it has been vaporized; but the means hereinset forth are preferred, inasmuch as a firm seating of the valve isinsured at all times, because it operates by a reciprocating movementwhich does not tend to grind or wear away the valve and its seat,

and at this point it will be further observed that while theneedle-valve 15 is preferably used the same may be substituted by anordinary stop-cock or cut-off valve arranged at a suitable point in theline of the generator-pipe 13.

The vapor-receiving pipe is adjustable and composed oftelescopically-related parts and alines with the pipe 13. The fixed partor section 19 connects with the T-coupling 9, and the adjustable section20 is slidably mounted upon the section 19, and its outer end is madeflaring, as shown at 21, to receive the tapering end portion 14: of thegenerator and insure a proper deflection of the vapor into the mainportion of the pipe or tubular section 20. The joint between thesections 19 and 20 is such as to prevent any escape of vapor and alsoprevent the movement of the part 20 except upon the application ofproperly-directed. force thereto. The distance between the delivery endof the generator and the receiving end of the adjustable pipe can beadjusted to a nicety, so as to prevent any escape of vapor and insure ittaking up the proper quantity of air to secure the combustion of thevapor at the burner.

The vapor-receiving pipe is located horizontally above the burner, andits receiving end, while located at an interval from the discharge endof the generator-pipe, is arranged in the path of heated air rising fromthe burner, whereby air which is inducted into the receiving-pipe by thedischarge of vaporized fuel into the latter is of such a temperature asnot to chill the vaporized fuel, and thus tend to return it to a liquidstate. The air which is thus intermixed with the vaporized fuel isapproximately of the same temperature as said fuel and is in a rarefiedcondition, adapting it to mix intimately with the vapor and, in fact,assist in securing such a complete vaporization of the fuel as willincrease the efficiency of the combustion of the mixture when it reachesthe burner-tip.

The burner is composed of a number of cooperating parts, among which isthe body portion, consisting of a tube 22, having a series of slots oropenings 23 in its sides, at its lower end, and a thimble 24:, whichmakes screw-thread connection with the vertical branch of the T-coupling12 and with the lower end of the tube 22. A plate 25 is located about atthe juncture of the tube 22 and thimble 24 and is provided with minuteopenings for the escape of the vapor. A sleeve 26 is rotatably mountedupon the lower end portion of the tube 22 and is supported with thevapor to secure the requisite degree of combustion. A series of arms 28are secured to the sleeve 26 and curve upwardly and outwardly, and theirupper outer ends are bent, forming rests 29 to receive the lower end ofthe shade 30. The gallery 31 is secured to the outer end portions of thearms 28 and is formed with a cone 32, which is sup plied at its apexwith a ring or band 33, containing a wire or gauze piece 34 to preventthe flame entering the tube 22 when the burner is lighted. A cap 35 isfitted over the ring 33 and is supplied with a wire or gauze piece 36for a like purpose. to the part 34. The mantle 37 is suspended from aholder 38 in the ordinary manner, saidholder having adjustableconnection with the gallery 31 in the usual way. at their lower ends tothe outer end portions of the arms 28 and are connected at their upperends by a ring iOand, with said ring, constitute a holder for the shade.

The pipes '7 and 10 are closed at their ends,

so as not to admit of a passage being had therethrough. \Vhen the lampis in operation, the hydrocarbon passes from the reservoir or fount 1through the pipes land 6 into the generator 13 and is vaporized by theheat 5 from the flame, the vapor passing into the extensible pipe 19 20and thence to the burner through the pipe 11, where it is consumed. Inorder to start the lamp, it is essential that the generator be heated,so as to cause a volatilization of the hydrocarbon, and this may beefiected in a variety of ways; but it is preferred to have recourse to aspirit-lamp 41, which is suspended from either the generator or theextensible pipe. provided with a hooked plate 42 and a spout 43, thelatter being filled with wicking or any absorbent material. The body ofthe lamp is of box form and is filled with Wicking or any absorbentmaterial, so as to obviate dan- 11o the flame and said fount and issuspended from the T-coupling 5.

While the invention is shown applied to a suspension-lamp, it is to beunderstood that lamps of the bracket variety or of any style or patternmay have the invention applied thereto, the vital feature being thegenerator and extensible vapor-receiving pipe located above the flameand having connection with the fount and burner, respectively,

whereby the hydrocarbon is supplied to the generator and is vaporized bythe heat of the flame, and the latter is supplied by the hydrocarbon inthe volatilized state to the burner.
